Operating Manual ENV216
3560.6550.12 -01- 3.4 E-1
Operation with non-standardized voltages
For measurement tasks on voltages that are outside the normal mains voltage ranges (e.g. <100 VAC)
and for operation on d.c. (max. 50 VDC) the ENV216 control circuit is powered externally by a plug-in
power supply.
Caution!
The d.c. voltage must not exceed 50 VDC!
The plug-in power supply is connected to the "EXT. POWER SUPPLY" socket (13). The input is reverse
voltage protected.
